Once we had the following code in Delphi:
B : String;
// complex code to calculate B. Prop is a property of the component.
Someone, while fixing a bug, introduced then
B : String;
Prop : String;
// complex code
And all of a sudden, our program no longer worked.
It took us a long time to find the error, namely an newly introduced local variable.
This kind of error is simply impossible in objfpc mode.
